GDPR is not only conflicting with some Blockchain use cases but with old-fashioned ledgers and paper-based accounting as well because the same principles apply here, too (an entry cannot be deleted, its effect can merely be reversed). If followed to the letter GDPR would've major repercussions on tax regulations because as a company you're legally bound to keep accounting records for at least 10 years whereas according to GDPR you're required to delete any record if asked by a person whose personal data appears in that record. The solution in that case is that GDPR only applies if it doesn't contradict other, already existing laws. So, where Blockchain applications facilitate legal requirements or don't manage personal data this should be perfectly fine but yes, other types of Blockchain applications are pretty much ruled out by GDPR.

You're allowed to retain the data where it is necessary to comply with other legal obligations, or to protect yourself legally (e.g. failure to pay invoices), among other reasons.

  That‘s exactly what I said. For instance, you have to retain accounting records such as invoices even if the invoice recipient asks you to delete the personal data on that invoice. Anything else would open up new avenues for tax fraud.

    You are allowed to ignore (refuse) to delete personal data from the Invoice: You may need their name to file suit against them for refusing to pay the invoice.
